Program Impact

Police Satisfaction

“The Framingham Police would not be able to fulfil its mission of keeping Framingham safe without the Jail Diversion Program... The ability to immediately divert low-level offenders away from arrest- and into treatment- benefits everybody.” Chief of Police, Framingham Police Department

Officers cite the immediacy of the response, their familiarity with the clinicians, and the clinicians’ ability to de-escalate situations as the most important components of the JDP model.

Culture Change

A study was conducted in Ashland, Sherborn, Holliston, and Hopkinton (HHS, formerly ASHH) to measure the effects of the Co-Response program on police officer attitudes towards the mentally ill in five different categories: Compassion, Kindness, Perceived Dangerousness, Community Inclusion, and Tolerance. One of the most significant changes was in the “Compassion” category, which increased by 15% after one year of the JDP program.

Overall, the program has shown a beneficial and positive impact for police officers and by default is impacting the way they view and respond to calls for service involving individuals in a behavioral health crisis. To view more data, please download our Culture Change fact sheet.

Program Replication

As communities have recognized the need for and value of police and mental health partnerships, Advocates has replicated and adapted its successful Framingham Co-Response model in several communities. The Advocates Co-Response team created a step-by-step toolkit to assist communities in the process of developing and implementing their own Co-Response programs. The toolkit is available through our Co-Response Training and Technical Assistance Center.
